By providing the detection means in the home bus controller, it is possible to incorporate a security unit that is not compatible with the home bus system into the home pass system using a pair of telephone lines that are considered to be used infrequently. .

[Example 11 An embodiment of the specific invention is shown in FIGS. 1 to 9.

In this embodiment, as shown in FIG.
Connect the pair line Lc of a-Lc directly to station #Il,
A standalone telephone 3 is connected to this bear@Lc. The stand-alone telephone 3 is one whose main function is to operate after answering an incoming call, such as an answering machine. In other words, when this answering machine is operating, people are usually not at home, so there is no need to take into account interference with other terminals 2 for the home pass system. German phone number 8! Bear 3! 111
．． By connecting to L and c, bare@L c can be used effectively.

By the way, an 8-pole, 8-core information outlet 5 shown in FIG. 2 is connected to the bare @ L t = L e @ D, and the terminal device 2 is connected to this information outlet 5. The terminal arrangement of this information outlet) 5 is as shown in Figure #43. However, the above single phone a3
Since it is connected only to the pair line Le, another outlet is required, and when changing the installation location of this independent telephone 3, there is a problem that some construction work is required.

Therefore, in this embodiment, a conversion adapter 6 shown in FIG. 2 is provided. This conversion adapter 6 has an information outlet at one end)
5 has a plug 6 connected to the tortoise, and the other end has a solo phone 8!
It is equipped with a monoera shack 6b to which 3 is connected. In addition, 4 pin or 6 pin
The terminal connected to the pair wire L6 of the plug 6a and the center terminal of the mono-F jack 6b are internally connected using a pin of the center line type. By using this conversion adapter 6, the installation location of the standalone telephone R3 can be easily changed by simply connecting the conversion adapter 6 to the information outlet 5.

By the way, in the above case, because the independent telephone FI3 was used for a special purpose, that is, as an answering machine, there were no problems such as interference with other telephone terminals of the home bus system. When making a call using a single telephone, problems may occur such as interference with other telephone terminals or the inability to make confidential calls.

In such a case, the HBCI may be provided with the following configuration, that is, as shown in FIG. 4, a usage detection circuit 7 that detects the usage status of the independent telephone If13 from the #i current;
A control circuit (not shown) composed of a CPU as means for prohibiting the use of the central office line l of the terminal 2 when using the standalone telephone fi3, and a control circuit (not shown) configured with a CPU that prohibits the use of the central office line The HBCI is provided with a relay contact r1 as an 11 connection control means for disconnecting the IIALC from the office line l.

Assuming that the standalone telephone 3 is now in use, the line current at this time turns on the e)) runnostar of the bidirectional photocoupler PC, and the output of the usage detection circuit 7 is as shown in FIG. 5(a). becomes low level. Therefore, in response to the low level output of the use detection circuit 7, the control circuit informs the terminal 2 that the station Ml is in use via the pair of wires for data transmission, as shown in FIG. 5(b). Command CD showing that there is
, and prohibits the terminal device 2 from using the central office line l. When the use of the central office line 1 (Q) by the standalone telephone 3 is completed, the control circuit sends a command CD2 to the terminal 2 via the pair line, indicating that the central office line 1 is vacant. 2 to use the central office line l.

On the other hand, terminal device 2 is the central office line! When using
As shown in 1), the terminal device 2 sends a request command CD using the station #Il to the control circuit via the bare MD, and the control circuit that receives this request command CD sends the request command CD as shown in FIG. relay contact ``1'' is opened, and then a permission command CD, which permits the use of the office line l, is sent back to the terminal device 2.After the second permission command CD is returned, the terminal device 2 uses the office line l. When the terminal device 2 finishes using the central office line l, the terminal device 2 sends a termination command CD to the control circuit, and the control circuit that receives this termination command CD5 sends the relay contact r, In this way, there will be no interference between the standalone telephone 3 and the terminal 2 of the home bus system, and confidential calls can be made.

By the way, in this type of home bus system, it may be necessary to make an extension call between the individual telephone 3 and the telephone terminal of the home bus system. In this case, H
All you need to do is configure BCI.

That is, as shown in FIG. 7, an extension power supply circuit 12 that supplies power for extension calls to each bear 1La-Le, a DC loop detection circuit 9 that detects the DC connection state of the individual telephone 3,
A pushbutton (PB) detection circuit 10 that detects a dial number input from the standalone telephone 8!3 and the standalone telephone 3
Bear @ the incoming signal that makes the ringtone sound from the built-in bell
An incoming signal sending circuit 11 that sends out to Lc, and a pair of wires Lc
and Bear M1-a.

Analog switches ASW, , ASW, which connect Lb.
and a control circuit 8 consisting of a CP [1] that performs signal judgment processing and operation control of the outputs of the above-mentioned circuits.

Now, when calling the telephone terminal of the home pass system from the stand-alone telephone 3 to make an extension call, proceed as follows.In this case, relay contact ``2'' has been switched to the extension power supply circuit 12 side. Off-hook of the type Wti machine 3 is detected by the DC loop detection circuit 9 as shown in FIG. 8(a), and the detection output is input to the uI control circuit 8.

Thereafter, the individual telephone 3 inputs one or a combination of dial numbers that specify an extension call. Note that each telephone terminal can also be individually identified using this dial number. The dial number at this time is determined by the control circuit 8 from the output of the PB detection circuit 10 shown in FIG. 8(b) if the individual telephone 3 is of the push-button type. In addition, if it is a dial type, please refer to Figure 8 (
a) The control circuit 8 determines the dial number from the intermittent output of the DC loop detection circuit 9 shown by the broken line inside. Thereafter, the control circuit 8 sends an extension calling command CD@ to the Wi-Fi terminal corresponding to the dial number, as shown in FIG. 8(d).

Then, when the telephone terminal on the calling side responds as shown in FIG. 8(d) (for example, a response command CD t is returned due to off-hook of this telephone terminal, etc.), the analog switches ASW, , ASW, , and connect one of the bare wires La and Lb to which the called telephone terminal is connected to the bare wire #iL L c. This allows extension calls.

When making an outside line call, it is sufficient to decide on a so-called O call, and in this case, the pair line Lc is switched to the central office line L side to enable the outside line call.

Conversely, when calling the independent telephone 8!3 from the telephone terminal, the procedure is as follows. In this case, as shown in FIG. 9(a), the telephone terminal issues an extension call request to the control circuit 8 via the bare MD. When the command CD for calling permission is returned from the control circuit 8, the dial number N for calling the independent telephone 8!3 is sent. At this time, the control circuit 8
The incoming signal S (for example, 16
Hz, 75V11FIs) from the incoming call signal sending circuit 11 to the bare #lLe, the built-in bell of the individual telephone 3 can be ringed, and the individual telephone 3 can be called. When the independent telephone 3 makes a response operation, this state is detected by the DC loop detection circuit 9, and the analog switch ASW is activated as shown in FIG. 9(d).

You can make extension calls by closing either ASW. In addition, although the above explanation has been made regarding the case of an extension call with the standalone telephone W13, it is of course possible to make an extension call with other telephone terminals, and a call interface circuit for making a call with a doorbell is also provided. If installed, it will also be possible to make doorbell calls. Furthermore, by changing the signal form, the incoming call signal S can be recognized as an extension call, and in the same way, a doorphone ringing tone can also be generated from the incoming call signal sending circuit 11.

By the way, the arrival of an outside line is detected by the network terminal (NT) 4 which has an interface function with station #il, which is originally provided in HBCI, and the control circuit 8 uses the output of this network terminal 4 to connect the relay contact ``,'' to the station line 1m. switch to enable outside calls.

[Embodiment 2J An embodiment of the related invention is shown in FIGS. 10 and 11. In the above-mentioned implementation, Bear@L c was used as a communication line for a single telephone 8!3, but this Bear@L, c for the security unit 13. That is, the bare wire Let is connected to the security unit 13, and the HBCI is provided with an audio detection circuit 14 that sends an alarm α from the security unit 13 to the HBCI and detects the alarm sound sent from the security unit 13.

If an abnormality is detected in the sensor 15 monitored by the alarm unit 13, the security unit 13 emits an alarm sound from the built-in speaker SP. Also,
At this time, an alarm sound is simultaneously sent to bear JJiLe. This alarm sound is detected by the audio detection circuit 14 in HBCl.
A command is sent to the terminal 2 to indicate that an alarm sound should be sent via the pair wire, and then to the analog switch ASW.

By closing, the alarm sound is transmitted to the bears 1iLa and Lb. In this way, unlike the security unit 13 of a conventional home bus system, there is no need for the security unit 13 to have the function of a terminal for home bus systems, and an existing security unit with a simple configuration can be used. There is interest that can be used. In addition, if the terminal I12 is equipped with a speaker, the above-mentioned alarm sound will be output from the speaker, and if the telephone terminal is a telephone terminal, a ring tone will sound in response to a command to send an alarm sound from the HBCI, and if the handset is picked up, , play an alarm sound from the handset, or similarly connect a radio or stereo to the pair line Lc to add BGMf to the home bus system.
You can also add i-functions.

[Effect of the Invention 1] As described above, the present invention connects one of the paired lines for telephone calls directly to the central office line, and connects the individual telephone to the pair of lines, thereby making it possible to connect the individual telephone in addition to the telephone terminal to the home. There is an advantage that it can be incorporated into a bus system, and that bare JI for telephone calls, which are considered to be used infrequently, can be effectively utilized.

In addition, in the rliM invention, a security unit is connected to one of the pair lines for telephone calls, and an alarm sound is sent out through the pair line, and an audio detection system detects the alarm sound sent through the pair line. By providing a means in the home bus controller, there is an advantage that a security unit not compatible with the home bus system can be incorporated into the home bus system by effectively utilizing the communication bearer 41, which is considered to be used infrequently.
